The FlaK 30 fired 20 mm rounds and the highest a round could go was about 3,668.5 meters. The FlaK 30 was also fed by a 20 round magazine which weighed about 9.5 kg full. The maximum range was about 2,000 meters and it usually required 7 men to operate. The cyclic rate of fire was 280 rounds per minute while the average was 120 rounds per minute. The FlaK 30 could traverse a full 360 degrees and the elevation ranged from -12 degrees to +90 degrees.
The total weight of the FlaK 30 system was 450 kilograms in its deployed state and 770 kilograms in its travel state. The total length was four meters. There were different types of ammunition that could be used by the FlaK 30, but often explosive rounds or tracer armor-piercing rounds were used. In order to travel, the FlaK 30 had two deployable wheels. The reliability of the weapon system suffered often, in the field the gun was prone to jamming. Also, by 1941, the gun was too slow to deal with most enemy aircraft.
